If i have architectural designs that i have come up with on my own time, What can i do with them?

You are generally not allow to practice architecture without a license. If you have some visuals that you feel will make a great building, bring them to an architect to be evaluated. He can complete your drawings in such a way as to make them useable for a construction company to build them and for a government agency to approve them. Good Luck - I can't wait to see it.
